A closed gas system initially has pressure and temperature of 86.6torr and 424K with the volume unknown. If the same closed system has values of 597torr, 1240mL and 455K, what was the initial volume in mL?

Expert Answer:

P1 = 86.6 torr

V1 = ?

T1= 424K

P1= 597 torr

V2 = 1240 mL

T2 = 455K

Using relation:
